"Impact Technologies proposes to develop and implement an integrated sensor validation software module that is capable of signal processing-based and model-based fault detection of sensor signals from F-100 engine test cell measurements. This advancedengine test cell monitoring software will perform real-time assessments of engine-installed transducers and will be implemented within the existing AEDC Data Validation Monitoring (DVM) system. Data validity will be rigorously analyzed using a combinationof signal processing and model-based techniques to ensure highly reliable signal fault detection and minimized false alarms.The engine sensor monitoring algorithms to be developed during this Phase II program will be tested and verified utilizing measurements taken from a Pratt & Whitney F-100 engine. The monitoring modules will have the capability to assess both transient andsteady-state engine data with generic signal processing and model-based technologies implemented within an open-systems, modular software architecture suitable for any 3rd party system integration. The software modules will focus on the detection andisolation of engine sensor faults. An autonomous software updating process will also be implemented during the program to allow the engine signature models and databases to be easily modernized over time."
